Features to know about

Installs Without Cutting or Splicing: Plug-In T-Connector Design

Getting trailer lights working doesn’t have to mean tapping into your vehicle’s wiring. The Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector plugs right into the factory tail light connectors behind the assemblies. There’s no splicing or wire tracing—just remove the tail lights, plug it in, and you’re ready for power.

Delivers Reliable Power: Powered Converter with Direct Battery Lead

This harness uses a powered converter that connects directly to the battery through the included fuse holder and hot lead. That setup isolates the trailer load from the vehicle’s sensitive lighting circuits, giving steady running, turn, and brake signals without overloading your system. The fuse holder adds protection for safe operation every time you tow.

Keeps Wiring Clean and Protected: Hidden 4-Flat Connector Storage

After installation, the 4-flat trailer connector can be stowed in an out-of-the-way spot inside the cargo area when not in use. That keeps it out of the weather and away from road grime until you need it. When it’s time to hook up, just pull it out and plug in your trailer lights.

Ready for LED Trailer Lights: Works with Modern Lighting Systems

The powered converter is built to handle LED trailer lighting, providing full function for today’s low-draw light setups. It keeps signals bright and consistent so your running, brake, and turn lights always work as they should when towing.

I have a concern, the wiring harness had been opened and stapled back together, I installed it but have not tested it yet, my hope is there will be no issues
by:
Mitsubishi Outlander
Welded up a hitch for my outlander sport and after I got it all bolted on realized there was no wiring. After looking on the internet for a few days I had given up, luckily I found etrailer. 98% of my cars manufactured are cvt’s so you can’t tow. Mine happens to be a Manuel, I talked to the dealer and he said they’ve never made this car in manual. I was very great full to find etrailer and that they somehow managed to make things work!

Still working flawlessly

The light wiring harness arrived in a few days. It came with good directions and I installed it in a couple of hours. The biggest challenge was running the hot wire up to the battery. But it plugged in to the existing wiring behind the taillights. Fairly easy to do yourself.

After purchasing the wire harness from etrailer I immediately went out to put it on my car. I was amazed at how easy it was to do. Every instruction was there with pictures and I was able to put the wire harness on with ease. The hardest part was running the power cord to thff we battery. Everything else was very easy. Thank you

Product fit my 2017 Mitsubishi Outlander Sport as described and was easy to install and get going. As usual etrailer was great to deal with.

I had a mechanic install this.
I'm never comfortable taking panels off the interior.
I'll rebuild a suspension, remove an engine, and replace an exhaust, but I don't fool with taking the interior apart.

Do you have a question about this Custom Fit Vehicle Wiring?
  • Will Trailer Hitch Void the Warranty for a 2017 Mitsubishi Outlander Sport
    I have both class II and class III trailer hitch options for a 2017 Mitsubishi Outlander Sport, the Curt Trailer Hitch Receiver part # C12048 for class II and part # C13079 for class III are what I recommend as they are both great bolt-on options assembled here in the USA. In order to complete your towing setup you'll need the Curt Powered Tail Light Converter part # C59236 for models without LEDs or part # C56127 for models with and the etrailer Ball Mount Kit part # 989899.

  • Comparing Trailer Wiring Options for a 2008 to 2012 Mitsubishi Lancer
    Many trailer wiring harnesses are vehicle specific so I would need to know the year, make, model, and trim level of the vehicle to recommend the best wiring harness. The Curt hitch you referenced, # 11479 is designed to fit a 2008 Mitsubishi Lancer except the Evolution and 2009 to 2012 Mitsubishi Lancer except Evolution, Ralliart, and Dual Exhaust models. For a 2008 to 2011, we only have the # 119178KIT available. For a 2012 you can use the # C56127. In this case the Curt harness, # C56127,...

  • Is .5 Volt At 4-Way Connector Normal After Curt Trailer Wiring Install Harness
    Sometimes there is voltage bleed like you mentioned with the Curt # C56127. If your # C56127 is otherwise functioning properly I'd say everything is fine.

  • 2013 Mitsubishi Outlander Sport LE Hitch and Trailer Wiring Recommendation
    For your 2013 Mitsubishi Outlander Sport the Curt Hitch part # C13079 would be a great choice as it is a Class III hitch with a 2 inch opening. For trailer wiring you would want part # C56127. If you plan on doing some towing you might be interested in etrailer ball mount kit # 989900. It comes with 2 ball mounts; one with a 3/4 inch rise or 2 inch drop and one with a 2-3/4 inch rise or 4 inch drop. It also includes a 1-7/8 inch ball, 2 inch ball, hitch pin with clip, and a storage bag. If...

  • Parts Needed To Tow a Trailer With a 2019 Mitsubishi Outlander Sport
    In order to tow a trailer with a 2019 Mitsubishi Outlander Sport you'll need a trailer hitch, trailer wiring harness, and ball mount/hitch ball. I have great options for all of these parts and will attach them below. In regards to the wiring, most smaller trailers only require a standard 4-way so this is likely what you will need. The 7-way is only required when the trailer has brakes. Curt Trailer Hitch Receiver part # C13079 Curt T-Connector Vehicle Wiring Harness part # C56127 (With...

  • Hitch Wiring Recommendation for Mitsubushi Outlander Sport 2015
    We have a custom fit for trailer wiring for a 2015 Mitsubishi Outlander Sport but it would require your vehicle to have LED taillights. For that you would want the part # C56127. If you do not have LED taillights you would want the part # C59496 instead. I checked our systems and we did not get any emails from your email address last week. If you didn't get an immediate email back saying we would be getting to your question as soon as possible then most likely the wrong email address...

  • Fit of Curt C13079 on 2021 Mitsubishi Outlander Sport LE
    According to Curt, their Class III # C13079 trailer hitch fits all models of the 2001 Mitsubishi Outlander Sport, including your LE. If you'll be towing with the hitch, If your Outlander has the LED taillights, Curt offers a plug and play trailer taillight wiring harness, part # C56127. If you have incandescent taillights, you'll need a splice-in harness like # C59496. You'll also need a ball mount like # D-28, a hitch pin like # PC3 and for a trailer ball, use # 19260 for a 1-7/8 inch...
